Regularly updated anti-virus software all seemed OK. Ad-aware said everything was fine.

This article discusses some of the ways the carbon cycle works, referring to the impact of human activities. Carbon, in the form of carbon dioxide (CO2), is the major greenhouse gas, implicated in climate change. Atmospheric CO2 concentration has increased by about a third since the start of the industrial revolution.

This time it is a tirade against the comments made in the September 2006 issue of PCW - about how Open Source software is too expensive for a small business to adopt.

Thu, 13 Jul 2006 22:36:01 GMT tas@sci-tech.co.uk http://www.sci-tech.co.uk/maths/fract.php Fractions, ratios and percentages all ways of expressing proportions. This means they show the relationship between two or more numbers. Tue, 11 Jul 2006 21:16:01 GMT tas@sci-tech.co.uk http://www.sci-tech.co.uk/maths/units.php If someone told you they had a piece of rope 19 long, would it mean anything to you? Or if they said their friend weighed 100? How about if you were going to a party 6 away? As you can see from these examples, it is important to have previously defined "units" with which you can make measurements and how important it is to quote them to people when you want to communicate information about measurements. Tue, 11 Jul 2006 21:11:01 GMT tas@sci-tech.co.uk http://www.sci-tech.co.uk/sonic_frogs.php A small Chinese frog species has been found to use ultrasound to communicate. Bats and dolphins and a few other species emit and hear ultrasonic noises but these are the first amphibians to have been found to have the capacity to do so. The research team was led by Albert S. Feng & M. Kowalczyk, University of Illinois at Urbana-Champaign. ...

The statement suggests that the extinction of the dinosaurs was a necessary precondition for the development of mammals and implies that mammals fill the same ecological niches as the dinosaurs. This account will discuss the concepts involved and consider the evidence concerning the mass extinction of dinosaurs. Tue, 6 Jun 2006 00:00:01 GMT tas@oustudent.me.uk http://www.sci-tech.co.uk/snortguide1.php Snort is a free network intrusion detection software. It is open source and free for personal use. You can download it from http://www.snort.org/dl/. The website describes it as the de facto open source Intrusion detection software. Here's a direct quote from the blurb at the top of its web page, to save me having to put this in my own words. Snort(r) is an open source network intrusion prevention and detection system utilizing a rule-driven language, which combines the benefits of signature, protocol and anomaly based inspection methods. With millions of downloads to date, Snort is the most widely deployed intrusion detection and prevention technology worldwide and has become the de facto standard for the industry. Thu, 8 Jun 2006 00:00:01 GMT tas@oustudent.me.uk http://www.sci-tech.co.uk/acidrain1.php Acid rain is a serious problem with disastrous effects. Each day this serious problem increases, many people believe that this issue is too small to deal with right now this issue should be met head on and solved before it is too late. In the following paragraphs I will be discussing the impact has on the wildlife and how our atmosphere is being destroyed by acid rain. Fri, 22 Jul 2005 00:00:01 GMT talesin@gmail.com http://www.sci-tech.co.uk/bigbangp1.php It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two types of models: Big Bang and Steady State. Sat, 17 Sep 2005 00:00:01 GMT admin@sci-tech.co.uk http://www.sci-tech.co.uk/lss1.php Within our natural environment we only have one real life support system - the planet Earth. The planet provides all the requirements we have for life, in one form or another. In order that we can see how this is the case, during this presentation we will look at the components that make up the life support system on Earth. Sun, 30 Oct 2005 00:00:01 GMT tas@oustudent.me.uk http://www.sci-tech.co.uk/globalwarm.php Global warming refers to a general rise in the Global Mean Surface Temperature across the Earth. Natural variations in climate between locations on the earth and over periods of time make it difficult to identify general changes except over a long time scale and a large area. A temporary rise or fall in temperature in one place is not evidence for or against a change in the world's temperature. Mon, 31 Oct 2005 00:00:01 GMT tas@oustudent.me.uk http://www.sci-tech.co.uk/seismic.php Seismic waves provide indications of deep planetary composition and structure through measurements of their speed of travel, recorded by seismographs located around the planet. There are two main types of seismic wave - body and surface waves. Of these, body waves are the most useful in determining the planets composition as they pass through it.

In fact there is something more than comic about a Trojan that first cuts off access to the Internet. A PC version of a suicide bomber? Sun, 02 Jul 2006 00:00:01 GMT heather@sci-tech.co.uk http://www.sci-tech.co.uk/ids.php This article presents a model Intrusion Detection System which can monitor output from programs such as Ethereal, to identify unauthorised attempts to access a network from the Internet. A miniature IDS was developed in C. The sample will read a network traffic output text file, to identify certain patterns that may indicate intrusion and to alert the systems administrator by providing a report on suspicious traffic. The paper suggests system administration policies to minimise an organisation's chances of falling victim to malicious intrusions.

Well the next windows vs linux battle will be fought soon. Windows Vista (formerly LONGHORN) is looking more and more like it will be released by the end of this year. Now I am sure many Windows users are over the moon about this new operating system which promises some of the things "real" (i.e Unix based ones) have offered for many years now... (continues) ...

After a brief hiatus last month (more down to lack of time than quality of magazines) we can return to the proper ranting about how terrible they all are.
